I am currently working on a new update system for cheetah itself to make that process as easy as possible. Then i will get to module updates.
My idea with that was to integrate it all into cheetah. Kinda like a phone. Phones have a app store which you can use to browse for new apps to install. My thinking was something similar for cheetah. A market built into cheetah where people can see whats available, purchase and install all from the admin area of cheetah.
